Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 7 - 8; Raggi dorsali molli (totale) : 12; Spine anali: 0; Raggi anali molli: 11 - 12; Vertebre: 27. This species is distinguished by the following set of characters: opercular spine long and cleithral spine very short; lateral-line scales 56-62; gill rakers 2 (+2 rudimentary) on upper limb and 12-13 (+5-6 rudimentary) on lower limb of first gill arch; bucklers 8-10 (1st and last are united) at the base of first dorsal fin; vertebrae 27. Colouration: a large black blotch between the 4th and 6th spines of the 1st dorsal fin; second dorsal fin with one longitudinal row of small dark pigmentations; inner surface of pectoral-fin with black membranes, white posterior margin and three small white
spots basally in fin, each ray creamy white (Ref. 131445).
